Climate and clothing
Northern New Zealand is subtropical and the south is temperate. The warmest months are December, January and February and the coldest are June, July and August. There is little variation between traditional seasons, although winter tends to receive heavierrainfall than the summer. These seasons, as in Australia, are opposite of those in the Northern Hemisphere and consist of spring (September to November), summer (December to February), autumn (March to May) and winter (June to August).
In summer, the average maximum temperature ranges between 20oC-30oC and in winter between 10oC-15oC.
In September, a jacket or coat will be necessary as some days and most evenings can be cool (12oC-18oC).
For official functions, it is suggested that representatives should wear business suits or national costumes.
